This article examines the relationship between the Orthodox doctrine of deification and the transhumanist concept of human enhancement. Can the doctrine of deification and the transhumanist aspiration to improve the human being be meaningfully compared without collapsing one into the other? There are reasons why such a comparison invites itself: in contemporary philosophical, bioethical, and religious studies literature, one increasingly encounters the language of transformation, perfection, and the transcendence of human limitation. Yet verbal similarity, by itself, proves nothing. Beneath it lie different accounts of what, precisely, is disordered in the human person, what the goal of human existence is, and by what path that goal may be attained. This study therefore proceeds from a stronger claim: the divergence between Orthodox theosis and the transhumanist project of human enhancement concerns not merely secondary motifs or descriptive vocabulary, but the underlying anthropological and soteriological foundations of the two models. Similarity of terminology does not in itself indicate any deeper inner affinity between them. To test this claim, the study employs textual, comparative, contextual, and dogmatic-theological methods of analysis. It expounds the positive content of the Orthodox doctrine of deification, reconstructs the conceptual structure of transhumanist human enhancement, and offers a comparative analysis of two models of human perfection with reference to their goals, means, understanding of personhood, body, freedom, virtue, death, and immortality. The article’s originality lies in approaching the problem not primarily within the framework of applied bioethics, but as a question concerning two distinct models of salvation and human vocation. It argues that theosis signifies the gracious transformation of the human person in communion with God and in the horizon of resurrection, whereas transhumanist enhancement is oriented toward the technically managed overcoming of limitation. The article concludes that this project is not a secular continuation of deification, but a different construction of hope that stands in tension with the Orthodox understanding of salvation.
